A recent change in nvidiafb caused nvidiafb_cursor to always return -ENXIO
instead of using the soft_cursor. This will happen if the parameter "hwcur"
is not set, which happens to be the default.

nvidiafb_imageblit converts the bitdata stream from big_endian to little
endian. This produces mirrored characters when machine is big_endian. Do not
endian convert on big endian machines.

If no EDID block is probed, if the display is digital and if no mode option is
specified by the user, get the timings by CVT instead of using the global mode
database.

Currently, fbcon assumes that the visual FB_VISUAL_MONO* is always 1 bit.
According to Geert, there are old hardware where it's possible to have
monochrome at 8-bit, but has only 2 colors, black - 0x00 and white - 0xff.
Fix color handlers (fb_get_color_depth, and get_color) for this special case.

This patch removes drivers that have hardware cursors from calling the
software cursor code. Also if the driver sets a no hardware cursor flag
then the driver reports a error it someone attempts to use the cursor.

In theory, there should be no more users of I2C_ALGO_* at this point.
However, it happens that several drivers were using I2C_ALGO_* for
adapter ids, so we need to correct these before we can get rid of all
the I2C_ALGO_* definitions.
Note that this also fixes a bug in media/video/tvaudio.c:
/* don't attach on saa7146 based cards,
because dedicated drivers are used */
if ((adap->id & I2C_ALGO_SAA7146))
return 0;
This test was plain broken, as it would succeed for many more adapters
than just the saa7146: any those id would share at least one bit with
the saa7146 id. We are really lucky that the few other adapters we want
this driver to work with did not fulfill that condition.

"At boot time the screen appears moved to the mid right portion of the actual
video pannel making the end of the line appears at the left edge... It simply
looks like moved half way to the right"
His particular hardware has a display with an unusual dimension (1920x1200) but
unfortunately has no EDID block. None of the entries in the global mode
database is correct for this particular display, and it particularly has
difficulty scaling up 640x480 (the default startup mode of nvidiafb) to
1920x1200 which causes the above described problem.
1, Add 1920x1200 to the global mode database.
2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the
EDID block is absent, no boot mode parameter is specified by the user, and
a flatpanel/LCD display is attached.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
